Train timetables are built such that trains can drive without any delay. However, in real-time, unexpected events such as overcrowded platforms or small mechanical defects can cause conflicts, i.e., two trains requiring the same part of the infrastructure at the same time. Currently, such conflicts are typically resolved by experienced dispatchers. However, it is impossible for them to fully anticipate the impact of their actions on the ...

The on-board collection of data related to train operation enables a better calibration of the current train motion models, which are fundamental for the elaboration of optimized train control solutions. Here, the possibility to implement an online calibration of train motion models at microscopic detail, i.e. to set the model’s parameters for the single train on the go, is explored. For this purpose, a comparison of different calibration ...

As the separation of vertically-integrated organizations in railway transportation, not only the competitive but also the collaboration between different operating companies and different modes should be considered emphatically in the rapidly changing multimodal transportation market. This paper tries to solve the Train Timetable Problem for serving Unpredicted Large Passenger Flow causing by the stop of air traffic in collaborating with ...

Train timetabling plays an important part in train management, not only for passengers, but also for train operators. In a highly dynamic transportation market, train timetabling is an essential bridge connecting the service supplier with transportation demand. However, in present operations, train scheduling without considering passenger demand can reduce competitive advantages of railway in the multimodal transportation market and will ...

A railway track near Rastatt, Germany, lowered on 12 August 2017 and caused a complete blockage of a sector of a major rail corridor, which lasted until 1 October 2017. This track closure had severe effects on the railway freight and passenger transport. This work investigates the effects on the Swiss railroad network, using openly available realized operation data. The behavior of the delays before, during and after the disruption is ...

This paper introduces distributed optimization approaches, with the aim of improving the computational efficency of an integrated optimization problem for large-scale railway net-works. We first propose three decomposition methods to decompose the whole problem into a number of subproblems, namely a geography-based (GEO), a train-based (TRA), and a time-interval-based (TIN) decomposition respectively. As a result of the decomposition, ...
